Gary Neal has been ruled out for Sunday's game against the Dallas Mavericks:

Gary Neal did not travel to Dallas with the team and will not play tomorrow vs. the Mavericks (@spurs on Twitter)

Neal was also out against the Houston Rockets also. The San Antonio Spurs seemed to not need him with their surplus of guards (mostly point guards), which is a good sign for the team and hopefully that'll give Neal as much time to let the injury heal.
